Some are still holding out hope that their relatives are alive — after all, no wreckage from the plane has been found, so it could have landed somewhere intact.

In a show of support for the passengers and their families, people have been putting up artwork in a viewing gallery at Kuala Lumpur International Airport.

Some of the pictures appear to have been drawn by children.

The artwork contains messages of hope — the one above shows the plane stuck in a tree with people climbing out of the windows, and another has the Bruno Mars lyrics to "Talking To The Moon" written on it:

I know you're somewhere out there ... Somewhere so far away ... At night when the stars light up my room ... I sit by myself talking to the moon ... Trying to get to you.

Here are a few more:

There were 239 people on board the plane when it vanished on its way from Kuala Lumpur to Beijing.
